Abstract :
We propose a new fast projection algorithm for stereophonic acoustic echo cancellation. This algorithm can be viewed as a generalization of the extended two-channel LMS algorithm which takes into account the correlation between the input signals. Moreover, this algorithm fits naturally with the framework of affine projection techniques extended to the two-channel case. Its computational complexity is less than half the complexity of the fastest two-channel RLS versions. Simulation results show the obtained performance
